I use to have a HF and bought the Pat's and really like the them so well that I installed a hydraulic toplink 

THAT'S THE WAY TO GO!!!
I decided bushings are cheap and once they go on they never have to come off of the old implements and stay Cat 2 ready.
I guess your view would be to just store the Cat 1 to Cat 2 bushings on the Cat 2 tractor and "bush up" on the implement as needed?
2. More head scratching comes from looking at the RFM. It is designed so the toplink attachment to what I'd describe as a swinging clevis presents more of a challange. If that were eliminated it looks like the RFM won't be able to follow the ground contours. With the swinging clevis arrangement the mower deck can ride over the ups and downs. Eliminating the swing action it looks like the deck will want to remain on the same plane as the tractor, raising the rear wheels off the ground when cresting a rise and rainsing the front wheels when coming to the bottom of a hill. How do you deal with that? I'm pretty sure I could come up with an arrangement that would still allow movement but am not anxious to redesign the mounting frame.
The diagram with the parts showed two nuts on each leg of the u-bolt for a total of 8. The diagram showed the side bolts as if were a piece of all thread, no cap/head for wrench, yet nothing like that was provided and there were four cap screws that fit the threaded holes. There were only four lock nuts so didn't seem logical that they were for the u-bolts.your extra nuts should be on the side bolts to act as jamb nuts. the lock nuts go on the u bolts.

Are you stating the nuts should be installed on the cap screw prior to running them in then once snug run the nut back against the PEC as a jamb nut?
IIRC, I used the lock nuts on the U-bolts and I did use nuts to jam the side bolts. BTW, my Pat's EC came with Allen type set screws...not hex bolts. Those bolts stick out way too far....
Do you have the hex bolts or Allen bolts?My instrution sheet showed the way i mentioned, mine was for a cat 1 though.
